I have been told it time to remove the dash and move a screw from one hole to another. This can be found on other sites. We are going to try it this weekend and see if it works.
The check engine light for the 2001 Isuzu Rodeo often comes on because of a sensor that is damaged or malfunctioning. The most common sensor is an oxygen sensor and when reset, this often allows the light to be reset.
An Oxygen sensor does not reset. You have to replace them and yes they are expensive.
The oxygen sensor can not be reset and must be replaced if defective.
The only way to reset the sensor light on a 1985 Nissan pickup truck is to disconnect the sensor wiring. After 60 seconds, put the wiring back in place.
Never heard of nor have I seen an Oxygen Sensor light. If you are referring to the Check Engine Light, then that light comes on when there is a problem with the emissions controls. It may be a bad O2 Sensor or it may be many other things. Don't assume the O2 sensor is bad. Depending on the year vehicle you own, which you failed to mention, you reset the light on most 1995 & older vehicles by disconnecting the battery for 5 minutes. On most 1996 & newer vehicle, you reset the light with an OBD2 scan tool.
Just reset your computer after replacing the O2 sensor.
Over time it may reset itself. But the best thing to do is reset it with and OBD2 scan tool.
There isn't a reset for the oxygen sensors. When a repair is made then you need to have the computer cleared.jd
Replace the sensorOnce you have changed the oxygen sensor just disconnect the battery cable for about 30 seconds and the computer will reset. If you don't make the repair it will never go away, that's what it is made for.
If an 02 sensor has failed, it can only be replaced. See "Related Questions" below for more
Buy the oxygen sensor and fix the car and get the light reset !
The sensor will cost around $75. It will cost another $75 to have it installed and the ECU reset.
